IMrRovsD SKATE TO ALL- WHOM IT MAY CONGERN:

l:Be it known thatv we, FERDINAND HAASE and WILLIAM ROsT, both of the town of Proviso, in the county of Cook, and State of Illinois, have invented a new and improved Adjustable Skate-Frame;" and we do hereby declare that the following is a full and .exact description thereof, reference. being had to the accompanying drawings, and to the letters of reference marked thereon Figure 1 representing the side view, and

Figure'Z the top view of the frame'. I t A vFigure-2., a vsection of one of the projections, B, and

,. Figure 4 a tool, N. e

The nature ofour invention consists in so arranging the skate-frame that by means of adjustable plates the frame'may be adjusted for feet of different sizes,` and be used Without straps. l

To enable others skilled in the art to make and use our invention, we will proceed to describe its construction and operation. 4 l l l i l A The frame, A is made of malleable iron, having projections B'B underneath, with slots a a, to put inl the runner and holes b I; for the rivets to secure the same. There are two slots, c c, cut across lthe frame A in itsx front part, and a slot, D, cut longitudinally in its hind part. Two plates,'E E, whose outward sides' are bent upwards in a groove-like manner, are attached to the frame by means of set-screws, F F, and byimean's of slots c c may be adjusted for a narrow or a `wide foot.' There are two more adjustablefplates, G and H, to adjust the frame to the length oi' the foot, andto attach the same to the boot-heel. Theplate Ghas prcngs ,g g`, projecting backward to enter the front part of the heel,'and a steel spring, g', to slide along as fur as is needed, and to catch into the rack I cut in'fthe skate-frame. The plate'H has prongsh' h, to enter into the back part of the heel, and the loop K, with a screw-thread cut inside, vthrough which passes an endless screw, S, supported by two of .the projections B B, and having a square head, t. 'A tool, N, combining a screw-driver, n, and a wrench, n', to'work the set-screws F F,and the head of the endless screw S, is used to adjustthe frame.

The operation consists in the following: The front plates EE, being adjusted tothe width of the foot, the plate Gr is shifted along the rack I accordingly, and the plate H moved more or less to suit the length ot'l the foot. Then the sole of the boot is driven tight intothe grooves of the plates E E, the prongs of the plate G are forced into the front side of the heel, and the prongs of the plate H, by ineans of the Wrench n', operated on the headt of the screw S, are driven into the 'back part of the'heeL and the skate is attached.

We propose to make'v three diii'erent frames, each capable of'being adjusted to four different sizes of feet.

Theadvanta es of our adust'able skate-frame consist in this, that the'same skates ma be used con .g J y I veniently bylpersous of different sizes and age, and that it does not require any straps, and therefore is more comfortable-for the foot. f v I What we claim as our invention', and desire to secure by, Letters Patent, is. A`skate-frame, provided with the laterally-adjustable toe-clamps E, the adjustable sliding-clip G, made to embrace the shank I, and being held in place by the spring g', engaging in the notches in shank '1, and the heel-clip H, operated by the screw S, al1 arranged to operate substantially as shown and described.

FERDINAND HAASE,

WILLIAM ROST.
